What's the model of the computer?Is it a desktop or laptop?Can you press and hold the Power on/off button for about 10 seconds, then turn it on, then what do you see first, if any?Do you have the windows 7 disk or recovery / restore disk?Please reply at the box below. Thank you.

It is a desktop.Nothing happens when i hold the start button and then switch. A quick flash comes up with the name of the monitor then every thing turns blac. The start button itself has a red circle on the bottom half and a blue circle at the top half. Eventually all will turn blue around the start button.The computer is a composite rebuild about three years old.I do not have the recovery disc for windows 7 professional although I have the authorization code

I need to go to my grandson's school presentation at 10:30 so will be off air from that time. How do I reconnect?
